Toffall'whom :'tma/ concern:

'Be it;l known .that 1,: Eine J. i JOHNSON, a Vcitizenfofithe United `States, residing at Chicago, in the l'county of Cook andState of Illinois, haveiinvented a'new anduseful Improvement in Controlling Mechanism for lVindowssfand @ther Movable Members, of which the following is arspeciiication.

My invention -.was devised more particutlarlyforiuse in controlling theposition oo Aoupied by a easement window, though it will b-e understood from the following description that it may kbe applied to use in con- .nection with any` movably-supported member of such character as tobe controlled thereby.

One of my Ob-jects-isto provide a novel, *simple and inexpensive construction of mechanism` whereby the movable member to be controlled thereby may be quickly actu- `ait-edito `vtheldesired position. Another obyject is to provide for vthe holding of the member in the position to whichiitis actin atedwand, in the case of a easement window `or the like, to positively hold'Y it in bothy open and closed positions; another object is to i lprovide for the quick movement of the inember and preferably the holding of the member inf adjusted position and, in the case of y a easement window, holding it in closed poy sition; and other objects aswill be manifest from the following description.

Inasmuch 4as l have` devised my invention for use more vparticularly in connection with easement windows, I have chosen to illustrate it as applied t-o suoli use yin the accompanying drawing, thoughnot with the' `intension of limiting ,the invention thereto.

`Referring to the accompanying drawings:

lFigure' 1`A is a plan sectional viewrof a easementwindow together withthe window casing to'which-myimproved controlling mechanism is applied, the mechanism being shown in plangthe window infthis'iigpreis-shownin closed position. Figure 2 is a view'likeV Fig. 1 sho-wing the window partly open. "Figure 3 is a section taken through' a part of the controlling device, the section being taken at the line' 3 on Fig. 5 and viewed'in the direction of the arrow. Figure 4L is a section taken atthe line 4- on Fig.' 2; and viewed `in the direction `of the vparty ofthe vcontrolling mechanismreferred to.

y sented at 8, Vto :adapt Vthe window' itowbe swung outwardly.

The particular illustrated embodiment of 'my [invention comprises: a rbearing member shown as formed of *an inverted' oup-Ishaped member 9 telescopedwith the.- upwardly-extending 4circular flange 104 of abase 'member 11 flatwise secured-tothefsill ofthe window frame, as by thefscrews 12. 'TheirnemberiQ which is thus swiveled upon 'the-base nieinber 11,l adapting-it to `oscillate fthereoin--is held against vertical displacementlfin any suitable; manner', as, .for example; Y by lscrews 13 carriedby the-memberi) andeXtendi-ng at theirrinner Yendsiinto aperipheraL groove lllocated in the .flange-10. Thefanember just described serves -as' a bearing for a44 rod 15 which extends y:diametrically therethrough and is; joiirnaled therein, thev rod 15 being vshown as' providedV 4withia ,sleeve 16 located within the: mem-bei' 9 and Asecured to the rod 151 against relativeilongitudin'al fmovement, as by means of a sorew17,;passing through-the sleeve and into any opening in the rod, this rsleeve therefore, pre-venting longitudinal; movement Iofv thei'rod. Itwis preferred that the sleeve: liibe' provided with a plurality of the screw-receivingpopenings, one. of whichis shown lat 18," forireceiving the screw 17, wherebyithe position fof the rod 15 lengthwise, inthe member V9, may be varied, to suit` dilferentconditi'ons.

The rod 15 is providedatthefend thereof betweenthe bearing member 9; and the window 7,'with afspiral groove provided on'its periphery, different. poritions'y Ofthis groove being of different pitch. In the construction shown the portion of the groove' :adjacent the shearing member 9is of relatively .short pitch, thiswportion` being shown ratgl9, and the portion ofthe groove tlierebeyiond,; and represented atrQO, vis of-relatively great pitfch,

`las represented. Thexrod;15extends,1'ataits grooved portion, into a tube-21 in which it is rotatable, this tube being pivo-ted, as indicated at 22, to the spaced ears 23 of a clip 24 secured to the inner face of the window 7, the tube 21 being'provided with apin 25 which extends into'the spiral groove in the rod 15. The opposite end of the rod is provided with a knurled head 26 to facilitate the rotating of the rod by the; operator,

this end ,ofthen rod being provided with a collar 27 rigidlysecured to a pin 28 shown as in theform of a key, lengthwise movable in a groove 29 in the rod 15 and extending *lengthwise thereof, the vwall of the member feet maybe augmented, if desired, by the operator sliding the collar 27 to a position in which the key 28enters the notch 50.Vv To 'open the Vwindow, the operator rotates the Vvrod in counter-clockwise direction in Figs. ',30 Y

3 and'll, with tlie'result of causingthe pin i f 125, togetherwith thetube 21 and the window 7, to be forced away from the'bearing member 9, the window swinging outwardly on .its hinges 8V. In thismovementV of the rod 15, the pin travels over the portion 19 of the spiral; grooverinto the portion 20 of this groove, Vand as the latter is of relatively great'pitch thewindow is caused to swing outwardly fatrelatively great speed, or, in otherV words, it requires only a comparativelyfew turns of the rod 15 to swing the window to fully extended position. Any

Y suitable means may-be provided, if desired,

50.- Y Vful in the holding of vthe window 7 in a posiand closed positions.

forV preventing'accidental closing ofV the window, Vas, Jfor example, by the action of wind, Vthe -means abovervreferred to, and of which the key 28 is a part, serving this purpose, these locking means, or other locking means for preventing the rod 15 :trom being reversely'rotated, being especially usetionjof adj ustment'intermediate its Jfull open rIlhemovement of the window 7 to closed positloninvolves, as willY be manifest, the

rotation ot the rod15 in clockwise direc- -Ntionirn Figs. Sand @the projection 25 traveling in the. spiral groove in the rod.

kThe Windowwill thusfbe caused to be swung substantially to closed position by a comparatively' few turns of Ythe rod. InV the v--inal rotation of they rod, however, the pin 25 enters the portion 19 of the spiral vgroove wherebythe desirable amount of leverage betweenthe rod'arid vthe window is preprovement is used in connection with a pivotally-supported window, as in the construction shown, the provision of the swivelled bearing member 9 permits of the 75 swinging of the rod 15, while maintaining journal connection therewith in the opening and closing of the window.

It has been above suggested that the connection of the rod 15 with the bearing mem- 80 ber 9 through the sleeve 16, permits of the adjustment of the rod 15 in this bearing member; It will be understood in this connection that by reason of the proportioning of the parts of the window frame or other condition presented, it may be desirable to position the bearing member at a greater distance from the window than as shown in `from the window than as shown, the rod 15 would be adjusted lengthwise in the bearing member 9 to a position in which the open`' ing 18 would register with the opening in the rod 15 for receiving the screw 17 and 95 the sleevesecured in thispos'ition. Any desirable `number of the adjustments referred to may be provided. lhile I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.

IVhat I claim as new, and desire to secure b yA Letters Patent, is: 1. In a device of the class described, in combination, a frame having a stop member, a closure pivotally mounted on said frame and impinging against said stop member, a rod having a spiral groove of varying pitch, a sleeve, one of said last named elements pivotally mounted on said frame and the second thereof pivotally connected to said closure, a stud rigidly carried by said sleeve and engaging said groove, the portion of the groove of least pitch coacting with said stud when the closure engages said stop member whereby to cause iirm engagement thereof, means to cause relative rotation between said 12o `rod and sleeve, and releasable locking means ing axial movement and permitting rotation of said member and means for pivotally attaching the other member to a hinged closure. l

3. In a device of the class described, in combination, a threaded member, a tubular member having means to coact With the thread of the first named member, a turret, means to mountsaid turret for free rotation,

one of said members passing through the Walls of said turret, means Within the turret and secured to said member preventing axial movement and permitting rotation of said member, means to lock said rotatable member to prevent rotation thereof, and means for pivotaily attaching the other member to a hinged closure.
